Mike Tyson will swap being ringside for being octagon-side for the bout

Former Telsa chairman Musk, 47, has been in the media for the wrong reasons after reaching a deal with the US Securities and Exchange Commission to step down as chairman.

He was accused of making "false and misleading statements" to investors on his Twitter account — and that comes after allegations he defamed a British citizen in Thailand after he helped save a group of boys stranded in a cave.

The Martian and Bourne series star Damon, 47, is also set to feature, days after mocking American Supreme Court nominee Brett Kavanaugh, who was accused of sexually assaulting several women.
